object Companion

Properties

curve

val curve: ECCurve

the curve on which this point lies

homX

val homX: ModularBigInteger

homogeneous X coordinate of point (X : Y : Z)

homY

val homY: ModularBigInteger

homogeneous Y coordinate of point (X : Y : Z)

homZ

val homZ: ModularBigInteger

homogeneous Z coordinate of point (X : Y : Z)

isPointAtInfinity

val isPointAtInfinity: Boolean

whether this is the additive identity (point at infinity). the point at infinity cannot be normalized.

Functions

asPublicKey

fun ECPoint.asPublicKey(preferCompressed: Boolean = false): CryptoPublicKey.EC

double

fun ECPoint.double(): ECPoint

adds this to this and returns the result

equals

open operator override fun equals(other: Any?): Boolean

hashCode

open override fun hashCode(): Int

minus

inline operator fun ECPoint.minus(other: ECPoint): ECPoint

normalize

fun normalize(): ECPoint.Normalized

normalizes this point, converting it to affine coordinates. throws for the point at infinity.

plus

operator fun ECPoint.plus(other: ECPoint): ECPoint

adds other to this and returns the result

times

inline fun ECPoint.times(v: BigInteger): ECPoint

inline fun ECPoint.times(v: ModularBigInteger): ECPoint

inline fun ECPoint.times(v: Long): ECPoint

inline fun ECPoint.times(v: UInt): ECPoint

inline fun ECPoint.times(v: ULong): ECPoint

toString

open override fun toString(): String

tryNormalize

inline fun tryNormalize(): ECPoint.Normalized?

normalizes this point, converting it to affine coordinates. returns null for the point at infinity.

unaryMinus
